A catalog of new blue stragglers in open clusters with Gaia DR3
Songmei Qin, Jing Zhong, Friedrich Anders +6
The high-precision {\it Gaia} data release 3 (DR3) enables the discovery of numerous open clusters in the Milky Way, providing an excellent opportunity to search for blue straggler…
Binary clusters in the Galactic disk I: Systematic identification and classification using Gaia DR3
Guimei Liu, Yu Zhang, Jing Zhong +3
Aims. We aim to identify and classify BCs using high-precision astrometric and kinematic data, and to investigate their physical properties, mutual gravitational interactions, and…
Insights into the 3D layered structure of nearby open clusters through N-body simulations
Kaixiang Lang, Yu Zhang, Hubiao Niu +3
Context. Open clusters (OCs) are important for understanding star formation, dynamics, and evolution. Previous studies have indicated a relationship between cluster structure and m…
Formation and evolution of new primordial open cluster groups: Feedback-driven star formation
Guimei Liu, Yu Zhang, Jing Zhong +3
The formation mechanisms of open cluster (OCs) groups remain unclear due to limited sample sizes and data precision. Recent advancements in Gaia astrometric data provide an unprece…
Unveiling the Binary Nature of NGC 2323
Songmei Qin, Jing Zhong, Tong Tang +9
As a well-known open cluster, NGC 2323 (also called M50) has been widely investigated for over a hundred years and has always been considered a classical single cluster. In this wo…
